46 Pontiac "sleeper"

[r.a.w.rods]

Ok now that the 63 F100 is coming to a close I have another project in the works. I was asked to take a 1946 Pontiac 4 door straight 8, three on the tree and turn it into some thing that would keep up with todays traffic, but had to be able to take it anywhere and buy parts on the go. So here is what we have come up with. Fatmans Mustang II front sub frame, LS1 GTO Engine and Trans. New Interior (stock looking) and leave the Old Paint that being the "SLEEPER LOOK". O and this is the first time it has been out of the garage in 15 years.

That is going to be way cool, looking forward to seeing the progress.

Bitchin car, will make a great cruiser. If you haven't already bought the fatman stuff here is an alternative. http://frameupwheelworks.smugmug.com...71705165_d8er6

It starts getting interesting at about page 3

It worked out really nice and is way beefier than a MII style setup.

Good Luck

Very nice car!

I have always like the Fatman stuff and because we not going weild on this thing I think it will work great for us.

Fair enough, to each his own, but.....How are you going to attach the fatman clip without welding?

[NASH JUDGE]

Love that car. super cool project...........

[twosaturns]

I see the wisdom of putting an LS in there, but wouldn't it be cool to keep the straight-8, but w/ a modern electronic distributor and fuel injection, and a modern trans.
just sayin'

looks to be a cool project, thanks for sharing!

[CruizinKev]

wow very nice project! I love that kind of builds!!!

[r.a.w.rods]

Fair enough, to each his own, but.....How are you going to attach the fatman clip without welding?

I never said that it would not be welded. Fatman takes my measurements and makes the front sub to be welded In.

First thing was to get the front clip off and set the car up level and get all the measurements.







Next was to cut the old front off after all the Measurements were checked again.



Now time to test fit the new front.




You can't see in the picutres but there are fish plates Inside the frame to help keep everything together, I will put them on the outside too just for over kill.



NOW CAN YOU GUYS SEE HOW THIS WORKS...LOL

A lot of guys use 2nd gen F body subframes to mate with early Pontiacs....I've seen a couple with very good results.
I'd have loved to do the same to my old 52 Pontiac, but the registration authorities here don't allow frame chops like this....grrrrrr.
Nice project!

Oh this is sweet! Great base ..

[r.a.w.rods]

Sorry on the delay of pictures guys. I have the car back down on all fours and have picked up the donor car ( 04 GTO ).








The Donor.






I will be selling the rest of the GTO when I get the engine and trans pulled.

[r.a.w.rods]

Well Ive got the LS1 pulled and every thing ready to mock up. Im going to try to use the stock GTO engine mounts and header but It looks like the GTO headers will not work ( you will see why later ).




Here you can see why I cant use the stock GTO headers, they come out on top of the frame. So it looks like Maybe a set of Sanderson LS1 Blockhugger Headers are the best bet. If you guys know of some thing better please tell, This is my first Ls1 Install.







Looks like the stock mounts are going to work out ok pluse keeping them helps with the steering rod witch is close to everything. Im just starting to make the mounts so dont worry gussets will be In place tomorrow, but for now you can see how its coming together.

I love cutting out mounts.


Gussets will come later when I can see were the steering rod goes.




Passanger side.


Driver side, see how tight.

Cool project. One thing I see that I think you need to address if you are not planning to. I don't see where you sleeved the clip so you need to weld some plates on the outside where your seam is. Just butt welding the frame is going to be too big of chance to fail.

[badbu68]

Can't wait to see more!

[Jake616]

Subscribed! This will be one very sweet build!

[1969CamaroRS]

Oh a sleeper! Very cool, keep the pics flowing

[r.a.w.rods]

I will, I just tacked them in place and bolted them on to see how they were going to line up with the frame. Pulse I wanted to hang them to see if the steering rod was going to be in the way of the boxing plates. If you guys see anything else please add.

[Conrad283]

Very cool

[BanditDave]

If you still have the GTO seats (front and rear) I would like first crack at them! Awesome build by the way!
